Abstract (en)
Embodiments of this application provide a motor and a vehicle. The motor includes a stator iron core and a flat wire winding structure. The flat wire winding structure is wound on the stator iron core through stator slots. Each stator slot has n layers of the flat wire winding structure. Each phase of the flat wire winding structure includes a first part and a second part, the first part occupies a layers in the stator slot, and the second part occupies b layers in the stator slot, and a≠b. In addition, in each pole of each phase of the flat wire winding structure, a stator slot wound with the first part and a stator slot wound with the second part are staggered by y1 slots. To be specific, the first part and the second part of each phase of the flat wire winding structure are staggered relative to each other by the y1 slots, an equivalent pitch between phase belts of a same phase of the winding located in two adjacent poles is y=y0-y1, and the pitch y is less than a pole pitch y0. In this way, the flat wire winding structure is a short-pitch winding, and further, when the motor runs, good torque fluctuation suppression effect is achieved, back electromotive force harmonics of the motor are reduced, and performance of the motor is improved.
